IApplication areas of BNJBearings
As a transmission component of mechanical equipment, the service life of bearings plays a significant role in enhancing productivity. Bearings are widely used in various fields,and here we list some representative industries.
SUITABLEFORAWIDERANGEOFCOMPLEX WORKINGENVIRONMENTS
Metallurgy Energy
Oil & Gas Aviation
Equipment such as steel smelting equipment, high-temperature meltingfurnaces,and steel rollingmillsrequire bearings with high temperature resistance due toprolonged exposure to high temperatures.
It is primarily used in high-temperature coalification pressure reactors, oil-immersed transformers,and other equipment. Thesedevicesare subjected to extremely harsh conditions,and thus,have stringent requirements for bearing quality.
The pumps and valves of the refining and chemical equipment,as well as the compressormain shafts, operateunder high loads, with corrosion-resistant sealingdesigns to ensure continuous production without any downtime.
It isprimarilyused in core componentssuchasaircraft engine main shafts, landing gear retraction systems,flight control system actuators,aviation hydraulic pumps,satellite attitude adjustmentmechanisms, and rocket turbo pumps
More fields:automotive gearboxes, kiln cars, motors, steel mills, boilers,transportation vehicles, spraying equipment, textile machinery,paper printing machinery, lifting machinery,etc.We sincerely provide you with professional and high-quality bearing supportingsolutions.
Heat Treating Li-ion New Energy Laundry
Carburizing furnaces,quenching tanks,tempering furnaces,mesh beltconveyor lines,vacuum heat treatment equipment,and cooling fans,among others.Bearings arerequired to maintainstable performance in harsh operating environments.
Bearingsare widely used in key positions such as the mixer spindle,coaterbackroll,rollerpress roll,and precision guide rail of the laminator in the lithium battery production line
The main focusis on the excellent sealing performance of key components such as the drum spindleofwashing equipment, therotatingshaftofdehydrators,the supporting roller of dryers,and the press dehydrator, underhigh-temperaturesteam conditions
